SPECIFICATION forming part of Letters Patent No. 570,341, dated October27, 1896. Application nea June 24,1896. sentir. 596,722. cto moda.)

To a/ZZ whom t mlm/,conceiva- Beit known that I, RICHARD STEWART SAM-PLE, residing at Huntington, in the county of Cabell and State of VV'estVirginia, have invented a new and Improved Bed Spring Frame, of whichthe following is a specification.

My invent-ion relates to improvements in bed-spring mattresses, and itprimarily has for its object to provide a mattress and frame of thischaracter of a very simple and economical construction and in which theseveral parts can .be easily assembled and the same effectively servefor their in tended purposes.

Myinvention also seeks to provide a springholding frame so constructedthat it can be readily adj usted to fit bed-frames of different sizesand to whichthe springs are conveniently connected in such a manner asto admit of the ready adjustment of the frame portions without affectingthe general arrangement or efficiency of such springs.

With other minor objects in view which will hereinafter be referred to,my invention consists in an improved bed-spring mattress embodying thepeculiar combination and novel arrangement of parts, such as willhereinafter be first described in detail, and then specifically pointedout in the appended claims, reference bein ghad to the accompanyingdrawings, in which- Figure l is a plan View of my improvementJ the framemembers being shown extended in dotted lines. Fig. 2 is a plan View,parts being in section, of one end thereof. Fig. 3 is a perspective viewof one corner of the frame. Figs. I and 5 are detail Views hereinafterparticularly referred to. Fig. 6 is a longitudinal section taken on theline 5 5 of Fig. l, and Fig. 7 is a transversesection taken on the line6 6 of Fig. l.

Referring to the accompanying drawings, in which the same letters ofreference indicate like parts in all the figures, A A indicate the sidebars of the mattress-frame, which in practice are made of the standardlength to suit. The bars A A at the ends have recessed or seat portionso, d, the inner ends of which form guides a a for the inner crossbars Cwhen the side bars A A are drawn to their innermost position, as shownin Fig. l.

By reference to the said Figs. l and 2 it will be observed the side barsA A are joined at the end by the cross-bars BC, which `are arranged inpairs and joined with each other and to the bars A A in such a manner asto admit of a ready lateral extension of the frame to suit beds ofdifferent widths, such bars B and C being each joined at one end to thebars A by the bolt-and-nut connections D E, the bar B being joined atone end to the bar A at one side, while the adjacent bar C is joined tothe other bar A at the opposite side. The cross-bars B have each ahorizontal slot b (see Fig. 2) for t-he passage of the bolts F F, whichalso extend through the bars C C and are held in a proper position bythe nuts and washers ff, as shown.

G G indicate the top or supporting coilsprings, which are joined at oneend g to the cross-bars B, while their opposite end g is secured to thecross-bar C at the opposite end of the frame, as shown.

H indicates a series of spring-truss braces, arranged, preferably, onebetween each pair of coil-springs G, which have their ends 71, and 7Lconnected to the bars B and C like the springs G, and which have theirends terminating in coil-spring portions h2, while the central orintermediate portion h3 is straight and forms a truss member which isadapted to pass under a pair of supplemental transversely-arrangedspringbraces J, each of which consists of a pair ot' cross-slats J J',held spaced apart by the spiral springs J2, such braces J being heldbetween the springs G and H, as clearly shown in Fig. 6.

By providing cross-spring braces J and combining them with springs G andH in the manner shown it is manifest that such members J will not onlyserve to hold the several springs G and H under a proper tension andrigidity, but also add increased strength to the mattress portion withan increased resiliency or spring action for the several spring members.

Vhile I have shown but two transverse braces J in the drawings, it ismanifest three or more may be employed.

K indicates tension or truss rods, which are secured to the inner edgeof the inner crossbars B and C, as shown. The transverse wires K arespaced from the bars C at points interme- IDO diate of their terminalsby stout blocks arranged on the inner edges of the bars C.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought the advantages of my improvementwill readily appear. It will be observed that by adjusting the bolts Fthe frame can be quickly adjusted laterally, the peculiar connections ofthe springs G and H admitting of such adjustment without affecting thegeneral arrangement of such springs or their operative condition.

The general structure of the frame is very simple, of a few parts, whichcan be set by any one Without the aid of tools, except a Wrench totighten or loosen the nuts.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The combination of the side bars, the cross-bars arranged in pairs ateach end of the side bars and adjustably connected together, one bar ofeach pair being secured to one side bar and the other bar being attachedto the other side bar, the parallel supporting coilsprings secured attheir terminals at one side of the bed-bottom to the inner bar of onepair of cross-bars and to the outer bar of the other pair and reverselyarranged at the opposite side of the bed-bottom the truss-Wires Hextending the entire length of the bed-bottom, located between thesupporting-springs and connected to the cross-bars in the same manner,and the spring-braces interposed between the supporting-springs and thetruss-Wires and supported by the latter substantially as described.

2. An improved spring bed-bottom coinprisiug a pair of side bars A A apair of crossbars B B a second pair of cross-bars C C a pair of saidbars B and C being disposed at each end of the frame and held forlongitudinal adjustment, the bar B at one end being Xedly connected toone of the side bars, the bar B at the other end being fixedly connectedwith the otherside bar, the bars C being similarly connected to suchside bars but in a reverse manner to the bars B, the coil-springs Ghaving one end connected with the crossbar B at one end and the otherend connected with the bar C at the opposite end of the frame, thetruss-Wires K connected similarly to the cross-bars B and C and thespring-braces J consisting of a pair of slats J held spaced apart bysprings J 2 all arranged substantially in the manner shown anddescribed.

3. An improved spring bed-bottom coinprising the side bars A, a pair ofcross-bars B and C at each end the cross-bars B being iiXedly connectedat one end to the side bar A at one side, the cross-bar C being iixedlyconnected at one end tothe opposite side bar A, the bars B, havinghorizontal slots, the bolt connections F the coil-springs G having oneen d connected with the cross-bar B at one end and the other endconnected to the crossbar C at the other end, the truss-Wires Hconnected similarly to the cross-bars B and C, and the spring-braces Jconsisting of a pair of slats J held spaced apart by springs' J 2, allbeing arranged substantially in the manner shown and for the purposesdescribed.
